The Claim

Creatine monohydrate supplementation does not significantly improve depressive symptoms in adolescent females with major depressive disorder who are already taking SSRIs, despite increasing frontal lobe phosphocreatine concentrations.

Cause and effect

In plain English

In adolescent females with major depressive disorder taking SSRIs, creatine monohydrate supplementation does not reduce depressive symptoms, even though it increases phosphocreatine levels in the frontal lobe.

See the scientific wording

Creatine monohydrate supplementation does not significantly improve depressive symptoms in adolescent females with major depressive disorder who are already taking SSRIs, despite increasing frontal lobe phosphocreatine concentrations.

Why this might work

Creatine increases the brain's energy reserve in the frontal lobe, but when antidepressants are already boosting serotonin, this extra energy does not change how mood-related brain circuits function.

  1. Study: The Effect of Creatine Monohydrate on Mental Disorders: A Systematic Review of Randomized Controlled Trials: Effet du monohydrate de créatine sur les troubles mentaux : examen systématique des essais contrôlés à répartition aléatoire

    In teenage girls with depression who are already taking antidepressants, taking creatine daily for eight weeks didn’t make them feel better than taking a sugar pill — even though it changed a brain energy marker. So the study agrees with the claim.
